previous lawsuit in Louisiana was dismissed in December over legal standing issues.
Also, a new lawsuit in Ohio does not seek the legalization of same-sex marriages at the state level there. Instead it seeks to have the names of both parents listed on birth certificates when an Ohio or out-of-state adopting couple are legally married elsewhere. This Ohio case would expand on an earlier Federal judge's ruling that Ohio must list same-sex spouses legally married elsewhere on Ohio death certificates. That case is being appealed.
And today a Federal judge in Texas is hearing a challenge to that state's same-sex marriage ban. Nevada's Attorney General also announced she will not defend Nevada's same-sex marriage ban from a legal challenge there because of the ban's likely unconstitutionality.
UPDATE: Even as I posted this map over lunch, a Federal judge in Louisville, KY, ruled that my home state of Kentucky must recognize same-sex couples legally married in other states. This particular lawsuit did not address whether same-sex couples could marry in Kentucky. So now Kentucky will either join Oregon in recognizing same-sex couples married elsewhere or join Utah and Oklahoma in appealing this ruling.
